LovellManufacturin corporation of Benns II, Erie, Pa., assignor to gCompany, Erie, Pa., a ylvania Application December 21, 1933, serial No.703,354 6 Claims. (Cl. 68-32) The present invention is designed toimprove the connection between a wringer and its support. Power wringersas ordinarily made are formed as a unit and secured to a wringersupport, this support usually providing a means through which totransmit the power to the Wringer. The wringer in use is subjected tovery frequent strains which are carried into, or through the connectionand which tend to loosen the connec- Yl0 tion between the Wringer andits support. With the present invention a stile of the wringer isprovided with projections which extend into sockets in the support,these projections and the Walls of the socket taking a large part of thestrain through the connection. Preferably the securing studs extenddirectly through the projection into the support, the heads of which arepreferably housed within the projection. Features and details of theinvention will appear from the specification and claims.

A preferred embodiment of the invention is illustrated in theaccompanying drawing as follows:-

Fig. 1 shows a vertical section of an end of a wringer and a part of itssupport on the line I I in Fig. 2.

Fig. 2 an end view of the wringer removed from its support and partly insection on the line 3-3 in Fig. 1.

Fig. 3 a front elevation of the wringer.

Fig. 4 a central section of a modication.

I marks the base of the wringer frame, 2 the side stiles and 3 the topbar. These are ordinarily constructed of sheet metal, the side stilebeing usually of box form with slots 4 on their inner faces throughwhich shafts 5 and 6 oi' wringer rolls I and 8 extend. Journal boxes 9and I 0 are arranged Within the stile, the upper journal box beingslidably supported therein and subject to pressure from the usualpressure spring II.

The power shaft of the wringer is coupled ordinarily with a shaft I2extending through a support I3. 'Ihe support is provided with sockets I4on the face next the wringer stile and the wringer stile is providedwith projections I5 which extend into these sockets. These projectionsare preferably formed by striking them up in the sheet metal yformingthe outer side Wall of the box-shaped stile. Studs I6 extend throughopenings I extending through the walls of the projection and these studsextend into screw-threaded openings I8 in the support I3. Heads I9 ofthe 'studs are housed within recesses 20 formed at the rear of theprojections. It will be noted that the openings I'I and in consequencethe heads of the studs are directly opposite the slot 4 so that thestuds may be readily put in place through this slot and the studs set upby tools extended through the slot.

Preferably there is little clearance between the end of the projectionand the bottom of the recess and a slight clearance between the face ofthe support and the wall of the stile and the walls of the projectionsand recesses are slightly conical l0 so that as the studs are set upthere is a pressed engagement between the walls of the stud and theWalls of the recess which forms a very rigid and secure connectionbetween the support and the wringer. The slight resiliency of the metalform- 15 ing the rear stile as it is drawn up tends to maintain therigidity of the connection in use.

With this construction the connecting studs, or bolts, are entirelysealed so that the supporting walls of the wringer support may beentirely 20 free from obstructions thus making it easier to fabricateand to plate, or polish, and also permitting of a more attractivestructure and one more readily kept clean.

In Fig. 4 I have shown a modification in which 25 an outer wall 2a ofthe stile is provided with a slight indentation 2I which has an openingthrough it. A cup-shaped tting 22 is arranged in the opening in theindentation 2| and this is provided with a flange 22a which is arrangedin 30 the recess formed by the indentation. The fitting has an opening23 which is adapted to receive a stud 24 for securing the wringer to asupport. The stud head 25 is housed in a recess 26 formed by thefitting. 35

What I claim as new is:-

1. A wringer frame comprising a side stile of box form having a shaftreceiving slot on its inner side and a projection on the outer wall ofthe stile opposite the slot, said projection being 40 adapted to engagea recess in a wringer support and having an opening for receiving asecuring stud.

2. A wringer frame comprising a side stile of box formation having awringer shaft slot in its 4,5 inner Wall and a plurality of projectionsin its outer wall opposite the slot, said projection being adapted toengage sockets in a wringer support and having openings therethroughadapted to receive securing studs.

3. A wringer comprising a side stile of box form having formed on theouter Wall thereof a member of a projection and socket connection for asupport, the inner wall of the stile being slotted and the outer wallhaving a screw-receiving open- 55 ing opposite the slot in closerelation to the member.

4. In a wring-er, the combination' of a stile of box form having aprojection on the outer wall with a perforation through the projectionand a recess within the stile at the rear of the projec-V tion; awringer support having a recess receiving the projection and ascrew-threaded opening in alinement with the opening through therecess,Y the peripheral walls of the projection and recess beingincluded and in direct wedging contact;

and a screw extending throught the opening'in the projection into thescrewf'threaded opening` inv the support and having its head housed inthe recess, said screw being operable Ythrough the inner Wall of thestile.

5. In a wringer, the combination of a stile ofl box form in crosssection havingan opening in itsl inner wall, a wringer support; saidstile and wringer support having between them recess and projectionsecuring members having included peripheral walls in direct wedgingcontact and a screw extending through'the projection and walls 'of therecess and drawing said peripheral walls into engagement, said screwbeing opposite the opening in the inner wall of the stile and operablethrough said opening. l Y

6. In a wringer, the combination cfa frame, comprising a stile of boxform havingan outer Wall formed therein and a projection adapted toengage a socket in a wrin'ger'support, said pro-
